9-7
concerned about the behavior during the first few seconds rather than the first
few minutes. Nextlook at the response overa smaller time frame of 20 seconds.
impulse(sys,20)
Look at the plot from aileron (input 2) to bank angle (output 2). The aircraft is
oscillating around a nonzero bank angle. Thus, the aircraft is turning in
response to an aileron impulse. This behavior will prove important later in this
case study.
